REVOLVING SHOW-STAND.

SPECIFICATION forming part of Letters Patent No. 299,466, dated May 27, 1884.

7 Application filed December 21, 1883. (No model.) Patented in Canada January 15, 1884, No. 18,448.

To aZZ whom, it may concern.-

Be it known that we, SAMUEL Tnannnns OULP, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, manufacturing eweler, and THOMAS TIOKNOR, of the village of Arkona, in the county of Lambton, in the Province of Ontario, Canada, jeweler, have jointly invented a certain new and useful Revolving Show-Stand; and we do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to certain new and useful improvements in revolving show-stands; and it consists in the peculiar construction and combination and arrangement of parts, as hereinafter more fully described and claimed.

Figure 1 is a perspective View of our improved revolving show-stand, showing a portion of one side of it broken away to exhibit the interior construction. Fig. 2 is a longitudinal section of Fig. 1. Fig. 3 is an enlargeddetail showing the manner of attaching the adjustable head onto the driving-spindle and flexibly connecting the said head to the tube attached to the cylindrical case. Fig. 4 shows the arrangement of our device when the load is supported below the vesselcolr taining the floating case.

It is a well-established fact that a hollow cylindrical case-set in water supports a load equal to its displacement, while the power required to impart a revolving movement to the said cylindrical case need only be of sufficient strength to overcome the friction of the. water acting on the surface of the case; consequently a cylindrical case can readily be designed to support any load, the dimensions of the case being simply increased to accommodate the weight to be carried, and as the weight so carried is supported entirely by the water, a clock-movement or other mechanical power of little strength is suffi cient, and may be employed to impart to the cylindrical case the desired revolving motion.

In the drawings, A is a stand or vessel. of any suitable size, and preferably cylindrical in shape.

B is a hollow cylindrical case, desi ned to rest upon the water or other fluid contained by the stand or vessel A. This cylindrical case B is preferably provided with a coneshaped bottom, 0, which cone-shaped bottom of course projects below the surface of the water in the stand or vessel A, serving as a counter-balance to prevent any undue tipping of the show-tray D, which is fixed, as shown, to the top of the cylindrical case B. If required, shot or other ballast may be placed tending from a hole which it surrounds inthe to derive motion from the clock-movement,

and extends, as before stated, up through the tube F, from the top of which it projects,and has fitted onto it a head, I. The upper end of the spindle G is squared, so that thehead I, which is fitted onto the squared end of the spindle G, may be adjusted vertically on the said spindle, but cannot revolve on it. Therefore the revolving motion imparted to the spindle G by the clock-movement is conveyed to the head I, which, being flexibly connected by the cords or wires J to the tube E, as shown, conveys the movement of the spindle to the tube E, which, being connected to the case B, imparts the desired revolving motion.

' It is important that the head I shall be flexibly connected to the tube E or to some other part of the cylindrical case B, as the power of the clock-movem ent is so delicate that any friction other than that produced by the water supporting the case would be fatal to the effective working of our machine. The flexible connection permits any little lateral motion, while effectually preventing the contact of any of the moving parts with anything calculated to impede itsmovement. By fitting the head I to the spindle G, so that it may be vertically adjusted on the said spindle, as described, the vertical adjustment of the case 13, caused by the loading and unloading of the tray D, will not in any way affect the connection between the case B and its spindle G.

\Vhile we have designed our machine specially for use in connection with showstands, it will of course be understood that the same device may be adapted for various other uses. We therefore do not confine ourselves to its employment for the purpose herein specified, reserving to ourselves the right to adapt it for any purpose where it is desired to employ power of little strength for imparting a revolving motion to a heavy body.

\Ve may also mention that,although the fore going description describes the device arranged to carry the load above the level of the floating case, it will of course be understood that the same effect can be produced and the load supported below the level of the floating case. Such an arrangement is shown in Fig. 4, in which arrangement the spindle G derives its motion from a eloclcmotion or some other motive powerlocated above the floating caseB. The head I is attached to the spindle G in a similar manner, as shown in Fig. 2, and is also flexibly connected to the case B by the wires or cords J.

Instead of the show -tray D being located above the stand or vessel A, as shown in Fig. 1, we provide a rack, K, suspended below the vessel A by the cords C, as shown, which cords we consider the equivalent of that part of our spindle G shown in Fig. 2 as inclosed by the tube F, as they transfer the motion from the clock-work to the carrying device.

\Ve attach importance to the cone-shaped bottom 0, for by its use, if there is any tendency on the part of the tray D to tip over to one side, all that it is necessary to do to steady the same is to place shot or ballast in said bottom, when said ballast readily seeks the apex of the cone and prevents tipping of the tray, whereas in the devices of this sort as heretofore constructed, where the case was of the same diameter throughout, shot or other ballast would run to one side, and the more ballast used the more the tray would tip.

\Ve are aware of Patent No. 181,029, and makeno claim to the construction shown thercin.

\Vhat we claim as our invention is 1. A cylindrical case, B, supported by water or other fluid, and having a hole centrally located in its bottom,and atube, 5, extending upwardly from the said hole, in combination wit-h a tube, F, surrounding a hole in the bottom of the stand or vessel A, and extending upwardly into the tube 13, the tube F inclosing and protecting the spindle G, for transferring the motion from the clock-work to the carrying device, substantially as and for the purpose specified.

2. A cylindrical case, 13, having a coneshaped bottom, 0, designed to extend below the surface of the fluid supporting the said case as a counterbalance to prevent tipping ol' the tray 1), and contained within the vessel A, in con'ibination with driving mechanism arranged to impart a rotary movement to the said case, substantially as and forthepurpose specified.

S. A cylindrical ease, I supported by water or other fluid contained within a stand or vessel, A, the said vessel having a tube, F, extending upwardly from its bottom, to protect the spindle G of the driving mechanism, as specified, in combination with a head, I, adjustably fitted to the spindle and flexibly connected to the tube E, which encircles the tube F, which surrounds the spindle and is connected to thefloating ease, substantially as and for the purpose specified.

4'. The spindle G, connected at its lower end with the clock-movement II, and provided with the head I, adjustably fitted onto the said spindle, in combination with the cords or wires J, arranged to flexibly connect the head I to the floating cylindrical case B, substantially as and for the purpose specified.
